Electronic Data Systems Corp. agreed today to buy Portland-based software company Saber Corp. for $420 million. It's the second major Oregon technology company to be sold in the past month.

Saber makes software that government agencies use in processing driver licenses, voter registration and other services. It forecasts sales of $125 million this year, up from $57 million in 2006.

Saber employs 550 people in the U.S., including 270 in Oregon. Most of the Oregon employees are in Salem, Saber's former corporate headquarters, which remains the company's software development center.

Saber will become a subsidiary of Texas-based EDS, and will remain headquartered in Portland. Its management team will stay in place, according to EDS, which said it plans no staffing cuts.

Saber's sale follows the sale of Tektronix Inc., which Danaher Corp. agreed to buy last month for $2.85 billion.
